I have a problem with migration in this model. So this is my initial class Post, it works perfectly(migration worked):

Initial Class Post 

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE) 

    def __str__(self):
        return self.title

I want to add a new column:

photos = models.ImageField(upload_to="/images/", default = None)

I deleted all migrations and so when i used makemigrations it works, but when i try to migrate i get nothing:

PowerShell Result:

Apply all migrations: blog
Running migrations:
No migrations to apply.

When i try to fake migrations it also is not working:

PowerShell Result:

Target specific migration: 0001_initial, from blog
Running migrations:
  No migrations to apply.

After i run the server i get this error:

Trying to acces my local website:

Error during template rendering
In template C:\Users\Administrator PC\Desktop\mysite\blog\templates\blog\base.html, error at line 6

no such column: blog_post.photos
    {% load static %}
    <!DOCTYPE html>
    <html>
    <head>

        <!-- Required meta tags -->

        <link rel="stylesheet" type="text/css" href="{% static 'blog/main.css' %}">

        {% if title %}
            <title>Django Blog - {{ title }}</title>

Please help i don't know what to try more. Thank you in advance.

像这样在迁移命令中使用您的应用名称

python manage.py makemigrations blog
python manage.py migrate blog
